CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 578,587, dated March 9, 1897.

Applioationfiledhnu rya 1897. Serial No. 618,007. (No model.)

To all whmn it may concern:

Be it known that I, BENJAMIN W. TUCKER, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Oar-Trucks, of which the following is a specification.

The invention relates to improvements in car-trucks, and comprises, first, a novel transom adapted to be applied to the well-known type of diamond truck-frame, and, second, in certain novel features of construction pertaining to the pedestal-frames, within which are arranged the usual axle-boxes and springsockets of novel form.

The object of the invention is to improve the structure of the pedestals for diamond truck-frames and to produce a transom which will in all cases aiford the proper strength and rigidity and be capable of ready and secure attachment to the diamond truck side frames.

The nature and purposes of the invention will be fully understood from the description hereinafter presented, reference-being had to the accompanying drawings, in which Figure 1 is a top view, partly broken away, of a car-truck frame constructed in accordance with and embodying the invention. Fig. 2 is an end view, partly in section and partly broken away, of same. perspective view of one of the spring-sockets arranged over the axle-boxes. Fig. 4 is a bottom view of same. Fig. 5 is a bottom view of the upper plate, connecting the ends of the beams forming the transom. Fig. 6 is an edge view of same. Fig. 7 is a top view of a portion of a car-truck and illustrating a slightlymodified form of transom, this figure showing channel-beams instead of I-beams, as illustrated in Fig. 1. Fig. 8 is aside view of same, and Fig. 9 is a perspective view of a further modified form of beams which may be employed for the transom.

In the drawings,A designates the side frame of the truck, one side only being shown, since the sides are duplicates of one another, and B the transom, which extends transversely across the truck and connects the opposite sides of the latter. The side A is of the wellknown diamond type and comprises the up- Fig. 3 is a detached per and lower bars (lettered O D, respectively) and the inner bars, (lettered E F,respectively.) At the ends of the side A are the pedestals formed of the vertical bars G H, which are secured between the bars E D by means of the vertical bolts I, which extend downward through said bars G H and receive upon their lower ends the securing-nuts J. The bars G H have upon their upper and lower ends the heads K L, which are grooved to fit upon the upper bar E and lower bar F of the truckframe, as indicated by the dotted lines in Fig. 2. The grooves or recesses formed in the heads K L of the pedestal-bars G H prevent any twisting of said bars G H and enable them upon the application of the bolts I to become rigidly secured and withstand all of the strain which maybe exerted against them during the use of the car.

Upon the facing sides of the vertical pedestal-bars G H are formed the rubbing and guiding flanges N, which receive between their lower portions the axle-boxes O and between their upper portions the socket P for the coiled spring Q, whose upper portion is confined within said socket P and whose lower portion is seated uponthe upper end of the axle-box O. The socket P for the spring Q is provided upon its opposite sides with the vertical flanges R, which embrace the opposite vertical edges of the rubbing and guiding flanges N, and said socket P is upon its upper end formed with the gibs or flanges S, which embrace the opposite edges of that portion of the bar E closing the top of the pedestal-spaces. It will be apparent that when the socket P is in position, as shown in Fig.

2, it will remain stationary and be prevented from any twisting movement during the employment of the car. The pedestal-frame inclosing the axle-box and spring-s0cket is entirely durable, reliable, and convenient of use.

The transom forming a part of my invention is shown applied to the side frame A; but it will be constructed to completion before its application to the side frames. The transom illustrated in Figs. 1 and 2 is composed of the I-beams ct a, which at their center are con-, nected by a center bearing-plate b and at their ends are connected by the upper and lower plates b b, which preferably will correspond with one another, so that either may be used as the top plate or bottom plate. The beams Ct at extend at their ends outward be yond the sides A of the truck-frame, and the plates 1) b are substantially central with the bars A E of the side frame and are provided with the gibs or flanges d d to embrace the opposite edges of the bar A and bar E. The plates Z) are elongated in outline and not only extend inward and outward laterally beyond the side A, as shown in Fig. 1, but extend longitudinally beyond the beams to a, and said plates 1) are formed with the recesses e e to fit upon the beams a a, and with the aperturesf to receive the rivets g, by which said plates are rigidlysecured to the beams a a and made to permanently connect the latter. The plates e are also formed with the apertures h to receive the vertical boltst' "L 2', which pass through all of the longitudinal bars of the side A, and are provided with the securing-n utsj at their lower ends. The bolts 1?, as clearly shown in Fig. 2, pass through both of the plates 1) and rigidly connect the transom B to the side A. At the outer edges of the plates 1) are formed the vertical flanges m, which, when the plates 1) are passed home upon the beams to a, will abut against the ends of said beams, as indicated by the dotted lines in Fig. 1. Upon the transom B may be riveted the usual hangers n n for the inside-huh g brakes, (not shown,) and said beams 66 a may at the center of their lower side be connected by any suitable bottom plate riveted thereto, as indicated by the dotted lines in Fig. 1.

The transom will, as above described, be constructed to completion before being applied to the side A, and will consist, essentially, of the beams 01, a and the plates 1) 19 applied to their ends and rigidly connecting said beams ready for application to the sides A.

It is not desired to limit the invention to the use of the technical I shape for the beams a a, and hence in Fig. '7 I illustrate that channel-beams may be substituted for the I-beams of Fig. 1. In the employment of the channel-beams lettered q q in Fig. 7 I will make use of the short channel-beam sections rr, (see Fig. 8,) which will be riveted to the vertical web of the channel-beams and with the latter form at the ends of the transom the I- beam shape shown in Fig. 1. The short channel-beam sections 0" will, with the main portion of the channel-beams q g at their ends, enter the recesses e of the upper and lower plates 1) b, as shown by dotted lines in Fig. 7, and the plates 1) b will be securely riveted thereto in the manner above described with respect to the construction shown in Fig. 1.

The modification illustrated in Figs. 7 and 8 consists simply in using channel-beams instead of I-beams for the transom without changing the plates 1) b or the manner of connecting said beams and securing the transom to the sides A of the truck.

In Fig. 9 I illustrate a further modified form of beam which may be used for the transom, and this form of beam is substantially an I-frame having its upper flange at the inner side of the beam and beyond the top plate Z) sheared off, as shown in Fig. 9. Thus the beam illustrated in Fig. 9 is simply one of the beams CL shown in Fig. 1 with its upper flange at its inner side removed between the top plate I? at one end of the transom and the top plate b at the opposite end of the transom. I have thus illustrated three forms of rolled beams which may be employed in the construction of the transom forming a part of my presentlinvention in order to demonstrate that the invention is capable of modifications and that I include all these and analogous modifications within the scope of my invention as claimed.

In instances in which the circumstances will admit of the same the bolts i may pass downward directly through the plates 1) and also through the flanges of the transombeams.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a car-truck the vertical pedestal-bars G, H, having the guiding and rubbing flanges N and provided with apertures to receive the bolts I, combined with the axle box, the spring seated therein and the inverted socket having upon its opposite edges the flanges to engage the flanges N; substantially as set forth.
